# Commands

Slash commands are the deterministic path: they act immediately, without a model
turn. `/help` is the authority for the build you are running — this page
explains the ones worth knowing.

## Session and history

| Command | What it does |
| --- | --- |
| `/new` | Start a new session |
| `/sessions` | Browse and resume a past session |
| `/rewind` | Walk this conversation back to an earlier message |
| `/resume` | Resume this session's interrupted turn |
| `/compact` | Compact the current context |

`/rewind` is the recovery keystroke: when a turn goes wrong, go back to the point
before it rather than arguing with the model about it.

## Models and providers

| Command | What it does |
| --- | --- |
| `/login` | Authenticate a provider (API key or OAuth) |
| `/model` | Pick the conversation model and its effort |
| `/decision` | Pick the decision model — separate from `/model` |
| `/effort` | Pick reasoning effort for the active model |
| `/manager` | Switch between the provider set and Magpie — the walkthrough is in [Connecting the Magpie gateway](/cetas/en/configuration/magpie/) |
| `/quota` | Show quota information for the active manager |
| `/status` | Show agent, session, model, and manager status |

## Permission and context

| Command | What it does |
| --- | --- |
| `/permission` | Set the session's posture — see [Permissions](/cetas/en/configuration/permissions/) |
| `/ptc` | Select the programmatic tool-calling mode |
| `/skills` | Browse discovered skills by scope |

## Work

| Command | What it does |
| --- | --- |
| `/questions` | Review pending questions and answer one |
| `/answer` | Answer a pending question inline: `/answer @q3 yes` |
| `/board` | Open the Board dashboard in your browser (offers to enable workflows on first use) |
| `/board.stop` | Stop all local Board servers |

## Housekeeping

| Command | What it does |
| --- | --- |
| `/update` | Check for and install updates — npm installs only |
| `/pi` | Manage pi packages |
| `/exit`, `/quit` | Quit |

> **Not every command exists in every build**
>
> `/effort`, `/permission`, `/decision`, and `/help` come from
> composed extensions, so a build without that capability does not offer them.
> The shell-owned commands above are always present. `/help` reflects the actual
> set.

## Keys

| Key | Effect |
| --- | --- |
| <kbd>Esc</kbd> | Interrupt the running turn (denies a pending approval first) |
| <kbd>Esc</kbd> <kbd>Esc</kbd> (idle) | First clears the input, second opens `/rewind` |
| <kbd>Enter</kbd> while running | Queues the typed message as a follow-up |
| <kbd>Tab</kbd> / <kbd>Enter</kbd> | Apply the highlighted `@path` completion |
| <kbd>Ctrl</kbd>+<kbd>T</kbd> | Collapse or expand thinking blocks |
| <kbd>Ctrl</kbd>+<kbd>O</kbd> | Collapse or expand tool output |

If the agent asks a question, type the reply directly — `/questions` and
`/answer` are for the case where you want to pick one out of several.

`/permission <mode>` works mid-turn, which makes it the one command worth
memorising: it is how you clamp a session that is doing more than you expected.
